Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting technology, specifically to a double-sided adhesive tape with anti-counterfeiting markings. Background Technology

[0002] There are many counterfeit and substandard products on the market. Although relevant departments and manufacturers have taken some protective measures, counterfeit products still occur from time to time, leaving the interests of consumers and legitimate product manufacturers unprotected.

[0003] Currently, anti-counterfeiting double-sided tape placed inside products is one of the most important anti-counterfeiting methods. However, it is difficult to print or laser-etch patterns on ordinary double-sided tape. Due to the penetrating properties of adhesives, when printed or laser-etched patterns are applied to the adhesive surface using equipment, the adhesive melts into the patterns due to its penetrating properties, making the pattern information blurry and thus unable to be correctly identified.

[0004] Therefore, how to achieve the goals of anti-counterfeiting and anti-tampering using double-sided tape, while also clearly displaying anti-counterfeiting marks on the double-sided tape, has become an urgent technical problem to be solved. Utility Model Content

[0005] This application provides a double-sided tape with anti-counterfeiting markings to solve the problem of how to achieve the goals of anti-counterfeiting and anti-tampering when using double-sided tape, and how to clearly display anti-counterfeiting markings on the double-sided tape.

[0006] This application provides a double-sided adhesive tape with anti-counterfeiting markings, comprising: a transparent release film, a first transparent adhesive, a coating, a substrate, a second transparent adhesive, and a release film arranged sequentially; The coating is applied to the surface of the substrate, on which a visible anti-counterfeiting mark is formed; The first transparent adhesive is applied to the side of the coating away from the substrate; The second transparent adhesive is applied to the substrate and is on the opposite side away from the coating; The transparent release film is applied to the surface of the first transparent adhesive away from the coating, and the release film is applied to the side of the second transparent adhesive away from the substrate.

[0007] Optionally, the coating and the first transparent adhesive are bonded to each other at their bonding surfaces. When the items bonded by double-sided tape are separated, the first transparent adhesive, due to its stickiness to the coating surface, destroys the anti-counterfeiting mark.

[0008] Optionally, the coating is a photosensitive coating, and the material of the photosensitive coating includes at least one of photochromic material, photosensitive resin or fluorescent material.

[0009] Optionally, the substrate is a flexible film with a thickness of 0.005~0.2mm; the material of the substrate is at least one of polyimide, polyethylene terephthalate or polypropylene.

[0010] Optionally, the material of the first transparent adhesive and / or the second transparent adhesive is at least one of acrylic adhesive, silicone adhesive or rubber adhesive, and the light transmittance is not less than 90% and the thickness is 0.01~0.2mm.

[0011] Optionally, the transparent release film is made of polyethylene terephthalate and has a thickness of 0.005~0.2mm.

[0012] Optionally, the release film is made of glassine.

[0013] Optionally, the anti-counterfeiting mark is one, two, or a combination of three of the preset pattern information, QR code information, or text information.

[0014] Compared with the prior art, this application has the following advantages: This application provides a double-sided adhesive tape with anti-counterfeiting markings, comprising: a transparent release film, a first transparent adhesive, a coating, a substrate, a second transparent adhesive, and a release film arranged sequentially; the coating is applied to the surface of the substrate, on which visible anti-counterfeiting markings are formed; the first transparent adhesive is applied to the side of the coating away from the substrate; the second transparent adhesive is applied to the substrate and to the other side away from the coating; the transparent release film is applied to the surface of the first transparent adhesive away from the coating, and the release film is applied to the side of the second transparent adhesive away from the substrate.

[0015] This application provides a double-sided tape with anti-counterfeiting markings, comprising a transparent release film, a first transparent adhesive, a coating, a substrate, a second transparent adhesive, and a release film arranged sequentially. The coating is applied to the surface of the substrate, which serves as the carrier for the coating. A visible anti-counterfeiting mark can be formed on the coating, meaning the anti-counterfeiting mark is recorded on both the coating and the substrate, thus clearly visible on both surfaces. If the double-sided tape with anti-counterfeiting markings is applied to an item, when the item is removed, the anti-counterfeiting mark on the tape will deform and be damaged, becoming irreparable. This prevents the double-sided tape from being reused, thereby achieving the purpose of anti-counterfeiting and anti-tampering. Attached Figure Description

[0025] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In related technologies, many counterfeit and substandard products exist in the current market. Although relevant departments and manufacturers have taken some protective measures, counterfeit and substandard products still occur frequently, leaving the interests of consumers and legitimate product manufacturers unprotected. Currently, double-sided anti-counterfeiting tape placed inside the product is one of the most important anti-counterfeiting methods. For example... Figure 1 and Figure 2 The image shows an existing implementation of double-sided tape A, as follows: Figure 1 As shown, release films 50 are respectively provided on the upper and lower sides of the first transparent adhesive 20; or, as shown in the figure. Figure 2 As shown, a first transparent adhesive 20 and a second transparent adhesive 40 are respectively disposed on opposite upper and lower sides of a substrate 30, and a release film 50 is disposed on the surfaces of both the first transparent adhesive 20 and the second transparent adhesive 40 to form a double-sided tape A. The existing implementation of this double-sided tape has significant problems. On the one hand, the existing double-sided tape A is only used for adhesion and does not have anti-counterfeiting or anti-removal functions. On the other hand, even if anti-counterfeiting information is printed or laser-etched on the existing double-sided tape A, the process is difficult, and due to the penetrating properties of the first transparent adhesive 20 and the second transparent adhesive 40, when the printed or laser-etched anti-counterfeiting information is applied to the surface of the first transparent adhesive 20 and the second transparent adhesive 40, the first transparent adhesive 20 and the second transparent adhesive 40 fuse with the pattern under the action of their penetrating properties, making the anti-counterfeiting information blurred and unable to be correctly identified.

[0029] To address the aforementioned technical problem of achieving anti-counterfeiting and tamper-evident properties on double-sided tape while clearly displaying anti-counterfeiting marks, this application provides a double-sided tape with anti-counterfeiting marks, comprising: a transparent release film, a first transparent adhesive, a coating, a substrate, a second transparent adhesive, and a release film arranged sequentially; the coating is applied to the surface of the substrate, on which visible anti-counterfeiting marks are formed; the first transparent adhesive is applied to the side of the coating away from the substrate; the second transparent adhesive is applied to the substrate and to the other side away from the coating; the transparent release film is applied to the surface of the first transparent adhesive away from the coating, and to the side of the second transparent adhesive away from the substrate.

[0030] This application provides a double-sided tape with anti-counterfeiting markings, comprising a transparent release film, a first transparent adhesive, a coating, a substrate, a second transparent adhesive, and a release film arranged sequentially. The coating is applied to the surface of the substrate, which serves as the carrier for the coating. A visible anti-counterfeiting mark can be formed on the coating, meaning the anti-counterfeiting mark is recorded on both the coating and the substrate. Therefore, the anti-counterfeiting mark is clearly visible on both the coating and the substrate. If the double-sided tape with anti-counterfeiting markings is applied to an item, when the item is removed, the anti-counterfeiting mark on the tape will deform and be damaged, making it impossible to restore. This prevents the double-sided tape with anti-counterfeiting markings from being reused, thus achieving the purpose of anti-counterfeiting and anti-tampering.

[0031] Next, the double-sided tape with anti-counterfeiting markings provided in this application will be described in detail with reference to the accompanying drawings.

[0032] Figure 3 This is a schematic diagram of the structure of a double-sided tape with anti-counterfeiting markings provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of a single-piece double-sided adhesive tape with anti-counterfeiting markings provided in an embodiment of this application.

[0033] Figure 5 This is a schematic diagram of the structure of light irradiating double-sided tape according to an embodiment of this application. Figure 6 This is an exploded view of the double-sided tape provided in the embodiments of this application. Figure 7 This is a schematic diagram of the structure of light irradiating the coating on the substrate, provided in an embodiment of this application. Figure 8 yes Figure 7 A schematic diagram of the structure on which anti-counterfeiting marks are formed on the coating of the substrate.

[0034] This application provides a double-sided adhesive tape with anti-counterfeiting markings, such as... Figures 3-6 As shown, it includes: a transparent release film 10, a first transparent adhesive 20, a coating 30-1, a substrate 30, a second transparent adhesive 40, and a release film 50 arranged sequentially. The double-sided tape A with anti-counterfeiting markings has the transparent release film 10, the first transparent adhesive 20, the coating 30-1, the substrate 30, the second transparent adhesive 40, and the release film 50 arranged sequentially from top to bottom. It can be understood that the transparent release film 10 and the first transparent adhesive 20 are located above the coating 30-1 and the substrate 30, and the second transparent adhesive 40 and the release film 50 are located below the coating 30-1 and the substrate 30, that is, the transparent release film 10, the first transparent adhesive 20, the second transparent adhesive 40, and the release film 50 are respectively arranged on opposite sides (top and bottom) of the coating 30-1 and the substrate 30.

[0035] like Figures 3-6As shown, the coating 30-1 is applied to the surface of the substrate 30, and a visible anti-counterfeiting mark is formed on it. That is, the substrate 30 is the carrier of the coating 30-1, and the coating 30-1 is uniformly applied to the surface of the substrate 30, meaning the coating 30-1 is located above the substrate 30. Furthermore, in this embodiment, the coating 30-1 is a photosensitive coating. When the photosensitive coating receives light of a preset wavelength, it undergoes an optical response, forming a visible anti-counterfeiting mark on the photosensitive coating. This visible anti-counterfeiting mark indicates that the product with the double-sided tape A affixed is a genuine product.

[0036] In the embodiments of this application, such as Figure 5 As shown, the double-sided tape A with anti-counterfeiting markings can be sequentially arranged with the transparent release film 10, the first transparent adhesive 20, the coating, the substrate 30, the second transparent adhesive 40, and the release film 50 in corresponding positions, and then cut to an appropriate size as needed to form a single piece of double-sided tape A. Figure 4 As shown. Then, according to the specific requirements of the anti-counterfeiting mark, photolithography is performed on the double-sided adhesive tape A using a light-irradiation device. The light sequentially illuminates the transparent release film 10, the first transparent adhesive 20, the photosensitive coating, and the substrate 30. The photosensitive coating on the upper surface of the substrate 30 changes; the irradiated photosensitive coating vaporizes to form a hollowed-out area. The hollowed-out area contrasts with the substrate 30 in color, thus forming the designed anti-counterfeiting mark, as shown. Figure 6 As shown.

[0037] Of course, photolithography can also be performed directly on the photosensitive coating on the upper surface of the substrate 30. For example... Figure 7 As shown, firstly, a photolithography technique is used to photolithographically etch the photosensitive coating on the upper surface of the substrate 30. This causes a change in the coating; the irradiated photosensitive coating vaporizes, forming hollow areas. These hollow areas contrast with the substrate 30 in color, thus creating the designed anti-counterfeiting mark. Figure 8 As shown. Next, after photolithography, the first transparent adhesive 20 and the transparent release film 10 are sequentially applied above the substrate 30, and the second transparent adhesive 40 and the release film 50 are sequentially applied below the substrate 30 to form double-sided tape A. Finally, it is cut into single pieces of double-sided tape A of appropriate size according to user requirements, as shown. Figure 4 As shown.

[0038] In other words, such as Figure 5As shown, the entire double-sided tape A can be formed by sequentially arranging the transparent release film 10, the first transparent adhesive 20, the coating, the substrate 30, the second transparent adhesive 40, and the release film 50, and then subjected to light to form a visible anti-counterfeiting mark on the coating. Alternatively, it can be as follows... Figure 7 As shown, the coating is first applied to the surface of the substrate 30 and then exposed to light to form a visible anti-counterfeiting mark on the coating. Then, the transparent release film 10, the first transparent adhesive 20, the substrate 30, the second transparent adhesive 40 and the release film 50 are set in sequence to form a double-sided tape A with an anti-counterfeiting mark.

[0039] The coating and the first transparent adhesive 20 are bonded to each other at their bonding surfaces. When the items bonded by double-sided tape A are separated, the first transparent adhesive 20, due to its stickiness to the coating surface, destroys the anti-counterfeiting mark.

[0040] This can be understood as follows: the first transparent adhesive 20 is located above the coating, and the coating has an anti-counterfeiting mark. The bonding surfaces between the first transparent adhesive 20 and the coating, that is, the contact surfaces of the two, are bonded together. When someone attempts to separate items bonded by this double-sided tape A, due to the relatively high adhesive strength of the first transparent adhesive 20, the separation force cannot cause the first transparent adhesive 20 to detach from the coating. Instead, it tears or rips the coating itself. This is usually because the intermolecular forces within the coating are less than the adhesive strength between it and the first transparent adhesive 20. Moreover, the damage to the coating also destroys the anti-counterfeiting mark it carries. This damage is irreversible; once it occurs, it cannot be restored to its original state, thus achieving the purpose of anti-counterfeiting and anti-tampering.

[0041] The substrate 30 is a flexible film with a thickness of 0.005~0.2mm; the material of the substrate 30 is at least one of polyimide, polyethylene terephthalate, or polypropylene. The substrate 30 is a flexible film, and the photosensitive coating is uniformly applied to the surface of the substrate 30, that is, the photosensitive coating is uniformly applied to the flexible film, and the film thickness is 0.005~0.2mm, including the ends (the numerical range in this application includes the ends, which will not be elaborated below). Including the ends refers to a closed interval, that is, including the endpoint values ​​of the numerical range; in this application, "including the ends" has this meaning.

[0042] The material of the substrate 30 can be at least one of polyimide (PI), polyethylene terephthalate (PET), or polypropylene (PP), that is, the substrate 30 is a polyimide film, a polyethylene terephthalate film, or a polypropylene film, and its thickness is 0.005~0.2mm. The material and thickness of the substrate can be determined according to the actual situation, and will not be described in detail here.

[0043] The anti-counterfeiting mark is one, two, or a combination of three of the preset pattern information, QR code information, or text information. That is, it is triggered when the wavelength of the light irradiation device can pass through the transparent release film 10 and the first transparent adhesive 20 and illuminate the photosensitive coating; or when the wavelength of the light irradiation device directly illuminates the photosensitive coating. Upon receiving light of the preset wavelength, the photosensitive coating undergoes an optical response and forms a visible image, QR code, or text information, etc., as an anti-counterfeiting mark on the photosensitive coating. The anti-counterfeiting mark can be any one, any combination of two, or a combination of all three of the preset pattern information, QR code information, or text information.

[0044] The photosensitive coating material comprises at least one of photochromic materials, photosensitive resins, or fluorescent materials. Specifically, photochromic materials are compounds that undergo reversible or irreversible color changes under light irradiation. These changes can be reversible (e.g., spiropyran, benzoic anhydride), recovering their original color after the light source is removed; or they can be unidirectional (e.g., certain azobenzene compounds), forming a permanent color. Photosensitive resins are resin systems containing photoinitiators or photocrosslinkers, capable of polymerization, crosslinking, or degradation under light irradiation, leading to changes in their solubility, hardness, and other physical properties. Fluorescent materials are substances that emit visible light of a specific wavelength when irradiated by high-energy light (e.g., ultraviolet light). Fluorescence is characterized by the immediate cessation of luminescence after the excitation source is removed; phosphorescence is characterized by luminescence that continues for a period of time.

[0045] It is understood that the photosensitive coating may contain only one of the three materials: photochromic material, photosensitive resin, and fluorescent material, or it may contain any combination of two or three to achieve more complex functions. For example, combining photochromic material with photosensitive resin can produce a smart coating that can both change color and be patterned.

[0046] The photosensitive coating is applied to the surface of the flexible film substrate 30. A first transparent adhesive 20 and a second transparent adhesive 40 are also disposed on the upper and lower opposing surfaces of the substrate 30. The first transparent adhesive 20 is adhered to the side of the coating away from the substrate 30; the second transparent adhesive 40 is adhered to the side of the substrate 30 away from the coating. That is, the first transparent adhesive 20 is adhered to the coating, specifically on the side of the coating away from the substrate 30. Since the coating is on the substrate 30, the side of the coating away from the substrate 30 is the outer surface of the coating. The second transparent adhesive 40 is adhered to the substrate 30, specifically on the side of the substrate 30 away from the coating. Since the coating is on the substrate 30, the side of the substrate 30 away from the coating is the back side or the other side of the substrate 30. It can be understood that the first transparent adhesive 20 is adhered above the coating (outer surface), and the second transparent adhesive 40 is adhered below the substrate 30 (back side of the substrate).

[0047] The first transparent adhesive 20 and / or the second transparent adhesive 40 are made of at least one of acrylic adhesives, silicone adhesives or rubber adhesives, and have a light transmittance of not less than 90% and a thickness of 0.01~0.2mm, including the ends.

[0048] Specifically, the materials of the first transparent adhesive 20 and the second transparent adhesive 40 can be at least one of acrylic adhesives, silicone adhesives, or rubber adhesives. Furthermore, the materials of the first transparent adhesive 20 and the second transparent adhesive 40 can be the same or different, and the materials of the first transparent adhesive 20 and the second transparent adhesive 40 can be selected according to the specific working conditions.

[0049] The thickness of the first transparent adhesive 20 and the second transparent adhesive 40 is 0.01~0.2mm, and an appropriate thickness can be selected according to the specific work. Moreover, the transmittance of the first transparent adhesive 20 and the second transparent adhesive 40 is not less than 90%, that is, the transmittance of the first transparent adhesive 20 and the second transparent adhesive 40 is greater than or equal to 90%, to ensure that the wavelength of the light irradiation device can pass through the first transparent adhesive 20 to irradiate the photosensitive coating.

[0050] The transparent release film 10 is adhered to the surface of the first transparent adhesive 20 away from the coating, and the release film 50 is adhered to the side of the second transparent adhesive 40 away from the substrate 30. Specifically, after the first transparent adhesive 20 and the second transparent adhesive 40 are adhered to the coating and the substrate 30, the transparent release film 10 and the release film 50 are also adhered to the first transparent adhesive 20 and the second transparent adhesive 40. Specifically, one side of the first transparent adhesive 20 is adhered to the coating, and the transparent release film 10 is adhered to the other side of the first transparent adhesive 20, away from the coating. One side of the second transparent adhesive 40 is adhered to the other side of the substrate 30 away from the coating, and the release film 50 is adhered to the other side of the second transparent adhesive 40, away from the substrate 30.

[0051] The transparent release film 10 and the release film 50 are adhered to the first transparent adhesive 20 and the second transparent adhesive 40, respectively, to protect the adhesive surfaces of the first transparent adhesive 20, the photosensitive coating, and the second transparent adhesive 40 from contamination, scratches, oxidation, and moisture erosion. The transparent release film 10 and the release film 50 act like a "shield," ensuring that the protected surfaces are in their original, clean, and intact state before final use.

[0052] The transparent release film 10 and the release film 50 are attached to the first transparent adhesive 20 and the second transparent adhesive 40. When the transparent release film 10 and the release film 50 are peeled off from the first transparent adhesive 20 and the second transparent adhesive 40, the exposed first transparent adhesive 20 and the second transparent adhesive 40 can be bonded to the corresponding adhesive item.

[0053] Specifically, the transparent release film 10 is made of polyethylene terephthalate with a thickness of 0.005~0.2mm, including the ends. The release film 50 is made of glassine.

[0054] The transparent release film 10 is disposed above the photosensitive coating and the substrate 30 so that the wavelength of the light irradiation device can pass through the transparent release film 10 and the first transparent adhesive 20 to irradiate the photosensitive coating.

[0055] The release film 50 is disposed below the photosensitive coating and the substrate 30. The release film 50 may be opaque, but it is also possible for the release film 50 to be transparent. When the release film 50 is opaque, its material may be glassine, which is easy to peel off from the second transparent adhesive 40.

[0056] The above describes a double-sided tape A with anti-counterfeiting markings provided in this application. After the double-sided tape A is formed by sequentially configuring a transparent release film 10, a first transparent adhesive 20, a coating 30-1, a substrate 30, a second transparent adhesive 40, and a release film 50, the coating 30-1 is applied to the surface of the substrate 30. The substrate 30 serves as the carrier for the coating 30-1, allowing a visible anti-counterfeiting mark to be formed on the coating 30-1. That is, the anti-counterfeiting mark is recorded on both the coating 30-1 and the substrate 30, thus clearly presenting the anti-counterfeiting mark on both surfaces. If the double-sided tape A with anti-counterfeiting markings is applied to an item, when the item is removed, the anti-counterfeiting mark on the double-sided tape A will deform and be damaged, making it impossible to restore. This prevents the double-sided tape A with anti-counterfeiting markings from being reused, thereby achieving the purpose of anti-counterfeiting and anti-tampering.

[0057] It should be noted that although several structures, components, or units for implementing the relevant functions have been mentioned in the detailed description above, this division is not mandatory. In fact, according to the specific embodiments of this application, the features and functions of two or more structures, components, or units described above can be embodied in one structure, component, or unit. Conversely, the features and functions of one structure, component, or unit described above can be further divided and embodied by multiple components, structures, or units.

[0058] Furthermore, although the various components of the components or apparatus in this application and the mounting arrangements between them are described in a specific order in the accompanying drawings, this does not require or imply that the components or apparatus must be designed according to that specific component or mounting arrangement, or that all the components shown must be included to achieve the desired result. Additional or alternative components may be omitted, multiple components may be combined into one component to achieve the corresponding function, and / or a component may be decomposed into multiple components to achieve the corresponding function, etc.

[0059] Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.
